Bad Checksum?

[8100 Power]

I was trying to get a tune from my LBZ today and it said I had a bad checksum from a the tune after the download, it also said I would be able to reflash using that tune.

And help would be great! Thanks... :)

I get that error alot also, but it still loads the tune correctly. id also like to know what causes this

Can you guys please Email the files to support@efilive.com , and be honest when it comes to the history of what has been programmed in to the ECM, we know some handhelds will cause this error. I don't want to spend time looking for a problem in the EFILive software when one does not exist.

Cheers,

So that means both these trucks are stock? :angel_innocent:

No, i get bad check-sums on modified tunes. The "out of range" tab checks out fine. And after I click "ok" the tune loads fine and the truck runs fine.

This happened to me when I tried to download the stock tune off a customers truck who did not tell me he had a Bullydog programmer on it.

Nick, as with 99% of ECM's with this error, they are not stock. Keep it in mind before you get too concerned there is a problem.

I'm not worried about it, I just thought it might help as a heads up to others who run into the same problem.

No worries,
